Traffic congestion will continue to worsen and likely worsen at a faster rate than ever. People throughput and freight throughput have become critical issues for California and the rest of the nation. PATH has funded with approximately $125K a research project entitled "Evaluation of Bus and...

This report defines an architecture for Automated Highway System (AHS) capacity-optimizing traffic planning functions. It identifies major traffic planning functions useful for optimizing the capacity of one or more major AHS operating scenarios and organizes them in a robust architecture that...

This paper proposes a shuttle van service as the initial deployment Automated Highway System (AHS) target. The freeway portion of the trip is fully automated and a professional driver is required for off-freeway driving. Advantages from the viewpoint of of different deployment issues are...

In this paper, the authors study the capacity of key Automated Highway Systems (AHS) operating scenarios. The effect of the lane-flow rule, platooning or free-agent, as well as the lane barriers, on AHS capacity are studied. Special attention is paid to the interaction between the lane-flow rule...

This paper proposes an approach to defining evolutionary scenarios for the deployment of an Automated Highway System (AHS). Six dimensions of deployment difficulties are identified: technology, infrastructure, human factors, vehicle manufacturing and maintenance, insurance, and public will.

This report describes possible objectives for a Field Operational Test (FOT), to be conducted following the completion of the National Automated Highway System Consortium (NAHSC) mission in 2002. At that time, it is anticipated that there will be one or more FOTs in which ordinary drivers will...

This report documents findings from a series of studies investigating how Intelligent Transportation Systems (ITS) could be used to improve the integration of commercial vehicle operations (CVO) with governmental services and regulations within intermodal transportation management centers. After...

Transportation Management Centers (TMCs) are focal points for monitoring and operating traffic management systems. As new technologies are developed through research in Intelligent-Vehicle- Highway Systems (IVHS), these TMCs will assume increasingly more importance as command and control centers...

The objective of this paper is to develop a throughput model of a multiple- lane Automated Highway System (AHS) with lane changes. The paper uses deterministic approximations to model highway throughput, accounting for both longitudinal and lateral requirements. The model is designed to account...
